HENRY W. JOHNSON, OF MOPHERSON, KANSAS- SHO'CKER.

SPECIFICATION forming part of Letters Itlatent No. 739,084, datedSeptember 1 5, 1903.

Application filed March 5, 1903.

To all whom it may concern:

Be it known that I, HENRY W. JOHNSON, a citizen of the United States,residing at Mo- Pherson, in the county of McPherson, State of Kansas,have invented certain new and useful Improvements in Shockers; and I dohereby declare the following to be a full,clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to shockers for harvesting-machines; and ithasfor its object to provide an attachment which may be secured to the mainor binder frame in position to receive the bundles from the table andwhich mechanism or attachment after a predetermined number of bundleshave been contributed thereto will be automatically operated todischarge the bundles in upright positions and set them upon the groundin the form of a shock, the part-s of the mechanism then returning totheir original positions to receive other bundles. 1

Other objects and advantages of the invention will be understood fromthe following description and include the provision of structuraldetails to insure proper sequence of the steps of the operation.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the sev-' eralviews, Figure 1 is a perspective View of the machine with the partsthereof in position to receive the bundles. Fig. 2 is a side elevationof the attachment with the parts in position'to receive the bundles.Fig. 3 is a section on line 3 3 of Fig. 4 on a smaller scale. Fig. 4 isa plan view of the attachment in its final position of discharging theshock. Fig.

5 is an elevation showing the mechanism shown at the left of Fig. 2 andwith the latchfinger in engaging position. Fig. 6 is a rear elevation of-a part of the machine, showing the means for disengaging the latch.

Referring now to the drawings, the present Sh0Ck6l,WhlCl1 is designedfor attachment to the main frame of a harvester and binder, comprises aframe including the longitudinal sills 10 and 11, arranged in parallelrelation and connected at their forward ends by the cross-piece 12, thesill 10 having brackets 13 for attachment to the main frame 15 of theSerial; No. 146,404. (No model harvester and binder, while the sill 11is provided with a supporting-wheel 14. It will be noted that the rearend of the frame of the attachment is open. At the forward end of theframe of the attachment is mounted an oscillatory transverse shaft 16,having rearwardly-directed fingers 17, which lie between the sills l0and 11, and the rear or free ends of which fingers are designed to riseand fall as the shaft 16 oscillates. When the extremities of the fingers17 move downwardly to their limit, the fingers slant, so that thebundles which are discharged onto the fingers from the table of the mainframe may be readily moved from thefingers and at the same time swunginto erect positions.

To move a numberof bundles simultaneously from the fingers 17 anddeposit them in the form of a shock upon the ground, the followingmechanism is provided: A head 18in the form of a plate is provided, theends of the head being slotted, as shown at 19 and 20, to receive thestems 21 and 22 of the bundle-holding arms ofthe mechanism, these armsbeing shown at 23 and 24 and including cross-pieces 25 and 26 at theends of the stems, and from which cross-pieces extend the .pairs ofcurved members, as illustrated, the arms being so positioned withrelation to the head that when the plate is in horizontal position thecurved members of each arm will lie one above the other and when thehead is in vertical position the curved members of one arm will lievertically above the curved members of the other arm. As illustrated,the stems of the bundle-holding arms are pivotally mounted in the endslots of the head, so that the opposite ends of the arms may be movedtoward and away from each other to gripor release the bundles. Normallythe head is in vertical position wit-h the arm 23 below the arm 24 andin close relation to the extremity of the fingers 17, so that thebundles deposited upon the fingers from the binder-frame will lie withtheir heads upon the arm 23, and if the arms be then caused to grip thebundles and the head be rotated to carry the arm 2t forwardly of themachine and the arm 23 rearwardly'the bundles will be gradually movedinto erect position and ofi from the rear ends of the fingers. Thebundles may be then lowered to the ground and the arms operated torelease them and then raised above the tops of the bundles and moved totheir former positions as the machine progresses.

To hold the arm 23 against downward pivotal movement when in position toreceive the bundles, the stem 21 is provided with a finger 25, whichprojects beyond the outer face of the head 18, and in the path ofmovement in one direction of this finger is alatch or stop 26', which ispivoted to the rear face of the head 18 and isheld normally andyieldably in active position by meansof the helical spring 28, whichencircles the rod 29, attached to the pivoted latch, and rests with itsends against the latch and the eye 30, through which the rod is slidablypassed. When the latch or stop is raised against the action of thishelical spring, it passes from the path of the finger 25', so that thearm 23 may swing in a direction away from the arm 24 to release theshock, as hereinafter described. The arm 23 is held normally andyieldably against movement in a direction away from the arm 24 by meansof the helical spring 31, which is disposed between the inner end of theslot containing the stem and the adjacent face of the stem, the springbeing attached at both ends and having such strength that it will returnthe arm 23 to its normal position when the shock has been released.

To hold the arm 24 spaced to the maximum degree from the arm 23 when thelatter is in horizontal position, the stem 22 of the arm 24 has arearwardly-directed lug 2, which projects into the path of movement ofthe cam 33 on the rod 34, which is pivoted to one end of the head 18 andthrough the medium of which said head is oscillated on the shaft 35,which is slid-ably mounted in the diagonal slot 36 in the outer side ofthe frame of the attachment. The rod 34 is connected to the crank -arm37 on the oscillatory shaft 38, mounted at the forward end of the frameof the attachment and which is oscillated at suitable intervals from thebinder mechanism. As the rod 34 moves or swingsthe head 18 into verticalposition the cam 33 is carried into engagement with the lug at the endof the stem of the arm 24, and as this lug is carried around the underface of the cam it is depressed and the arm 24 is raised at its free endor moved away from the arm 23.

To hold the shaft 35 at the upper end of the diagonal slot 36, a cam 39in the form of a quadrant is formed on-the outer or rear face 18 andworks against the roller 40 on the pin 41, which projects from the innerface of the outer side of the frame of the attach ment, the cam being sopositioned that its curved face rests upon this roller when the head isin vertical position and continues to rest upon the roller until thehead has reached a horizontal position, when the cam passes beyond therollerand the head,with its arms,may then drop. Connected to the outerend or head of the shaft 35 is a spring 42, connected also to the post43 at a point above'the shaft, the strength of this spring beingsufiicient to hold the head, with its shaft, normally in raised positionand to permit the head to move downwardly only when the arms thereofbear the weight of a shock. When the shock is released, the springreferred to raises the head so that by operation of the rod 34 the headmay be rotated to run the cam 39 onto the roller 41, it being understoodthat in the rotation of the head the cam holds the headagainstdownwardmovement, due to the weight of the shock, until after theshock is moved to erect position.

As above described, the separate bundles are successively deposited uponthe fingers l7'and the arm 23, the arm 24 being held at the upper limitof its movement, while the arm 23 is prevented from pivotal movementaway from the arm 24. As the arm 24 is swung forwardly and downwardlyand the arm 23 rearwardly and upwardly by rotary movement of the head'l8the cam 33 passes from engagement with the lug of the stem 22, so thatthe arm 24 is released and its spring is permitted to draw it tightlyagainst the bundles and hold them between it and the arm 23 in the formof a shock. This rotary movement of the head with the arm is continueduntil both arms and the head are in horizontal position, at which timethe cam 39 has passed beyond its supportingroller, and the weight of theshock causes the arms and the head to move downwardly to deposit theshock with the bottoms of the bundles upon the ground. As the head 18travels downwardly it travels also rearwardly by reason of the diagonalor slanting direction of the slot 36, so that the latch 26 is carrieddownwardly and rearwardly and strikes upon the pin 44 at the side of theframe of the attachment, so that as the head continues downwardly thelatch 26' will be swung free from the lug or finger 25' to permit of thearm 23 swinging rearwardly or in a direction away from the arm 24. Thisrearward-swinging movement of the arm 23 acts to release the shock, andas the machine progresses the arm swings farther to the rear and is thendrawn along the side of the shock, and when the machine has passedbeyond the shock the spring connected with the stem 21 returns the armto its originalposition. As soon asthe arms deposit the shock, so thatthe head is relieved of the weight of the shock, the spring 42 raisesthehead, and therewith the arms, so that the latch 26 is raised out ofengagement with its stop-pin, and the latch is permitted to return toits normal or active position. At this time the lug or finger 25projects beneath the latch 26, so that the latch does not snap down intoits active position until after the spring of the arm 23 has returnedsaid arm to its normal or receiving position. After the head, with thearms, has been raised by the spring 42 the rod 34 returns the head tovertical position, with the ICC arms in position to receive the next lotof bundles, it being understood that when the head is thus rotated inits raised position the latch 26 is spaced such a distance from itsstop-pin on the frame of the attachment that it swings clear of thestop-pin. This is because the axis of rotation of the head has beenraised, in which position it is held during the return movement ordownward inove-.

zontal position the strap is released and thefree ends of the fingersare permitted to drop.

.When the shaft 38 is rocked in the opposite direction to return thehead to vertical position, the strap is drawn upon, so that the shaft 16is rocked to raise the free ends of the fingers 17.

With this construction it will be seen that by properly timing theoscillation of the shaft 38 the arms may be held in proper position toreceive a number of bundles and will then bemoved to erect the bundles,then to deposit them, then to release the bundles in the form of ashock, and finally to return to their original positions.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from the spirit of the invention.
